1. Energy consumption of open resources
When a computer is started, it will not always be in full load operation, so there will be a lot of empty work, so the power consumption in the empty work becomes a major technology of power management. . In Windows 7, the power consumption during the open period is effectively improved. When a certain hardware does not work, it will enter the low power state and achieve the goal of power saving. This technology is adopted in the CPU, hard disk, memory, and network sections. For example, a CPU with a full power consumption of 35w consumes almost zero power when it is empty, and this alone can save a lot of power.
2. Start the service by triggering
Usually the system service will start together when the system starts, and then stay in the backing and expect to call. In Windows 7, some system services are only triggered when they are triggered by some events, such as inserting a facility or changing the IP. This will reduce the number of long-running services in the backing history.
3. Enhanced Solution Power Management
Windows 7 integrates the latest power management technology that allows Windows 7 to dynamically adjust CPU performance based on current load conditions and performance requirements.
4. Adaptive display brightness adjustment
Microsoft indicates that the display will automatically turn off when there is no operation in 10-15 minutes. However, there will be more short-term operation in actual use, and in order to save energy, the technology will reduce the brightness of the display. In addition, it can use some sensing facilities to adjust the brightness of the display according to the ambient brightness.
5. Low Power Audio
Windows 7 will support Intel's low-power HD audio standard, which allows the codec to enter a very low power state. Windows 7 also supports the hang-up technique to turn off idle facilities, such as USB devices such as microphones and cameras.
6. Timer integration
At present, the solver achieves energy-saving goals by utilizing the gaps in the solution of the instructions, but most of the energy-saving technologies require a certain length of space to gain energy-saving motivation. This technology adds the time and effort of the solver by letting the Windows kernel terminate and concentrate on multiple timers that are more evacuated in the same effort.
In addition, Windows7 will reduce the frequency of non-critical back-end programs when the notebook is in use.
7. Bluetooth device power consumption improvement
When Windows 7 detects that the Bluetooth facilities are in a low power state, they will be temporarily turned off, that is, "removal hangs".
8. Network Facilities Power Improvements
The compatibility of the wireless network manipulator's low-power mode in Windows 7 has been enhanced, but it is only enabled when the wireless AP facility supports the low-power mode. Vista can't detect if it supports low-power mode in advance, which will cause wireless network connection to be interrupted. Windows 7 will survive this situation and will first detect if the wireless AP is supporting this mode before entering the low power mode.
9. Optimization of the use of the program
In addition to the improvements listed above, Microsoft has turned its attention to specific use occasions, including search, reading without networking and small games. The following is part of the optimization scheme for DVD playback:
Let the CPU maintain low power mode without affecting playback performance
Improve the power consumption of desktop window manager and GPU by transforming the architecture
Intelligence Data cache can reduce the speed of the optical drive
